tozsam has yet to learn the way of the Dremel
what about being built into a car design, the motion of the car would provide more than enough wind power. The amount of times I've been using my iphone satnav only to loose connection in the middle of nowhere, then when the connection finally comes back you hear the 'do a legal u-turn' and find out you have gone several miles in the wrong direction.

tozsam, that would be inefficient, you're in a car with a battery and an engine.
What you need is just an antenna on the roof.

not a bad idea, the sooner we start moving off of fossil fuels the better for us in the long run.

That's brilliant... so long as your value of "middle of nowhere" never exceeds "a third of mile from somewhere else that *has* got an Internet connection".

Um..?

They only *tested* it to .3 of a mile - standard Wi-Fi equipment with custom antennas has been known to reach multiple miles quite easily.

Plus, it'd be easy to combine this with mesh networking technology like LocustWorld: that way it only has to be near another non-Internet-connected Wi-Fi mesh node, which in turn is near another, and so on - until you eventually reach the one node in the village which *does* have an Internet connection.

Been doing this for years... but you would be surprised at how much power you need to generate for 100% up time and reliability. 200watt solar panel and 3kw of battery is needed to keep 4watts of radios running year round here in north Idaho.

Not really. If you need connectivity further out, you put several repeaters up, so the signal is carried along by the repeaters until it reaches your internet base station(s). It would, essentially, become a mesh network. It's how most rural internet access is provided. A company pays for a hard line to somewhere, then sets up a wireless mesh to cover the village.
